Let’s check out your problem:

Rosita is writing an explicit function for the geometric sequence:$\newline$$$80,40,20,10, \ldots$$$\newline$She comes up with$\newline$$$t(n)=160\left(\frac{1}{2}\right)^{n} \text {. }$$$\newline$What domain should Rosita use for $t$ so it generates the sequence?$\newline$Choose $1$ answer:$\newline$(A) $n \geq 0$ where $n$ is an integer$\newline$(B) $n \geq 0$ where $n$ is any number$\newline$(C) $n \geq 1$ where $n$ is an integer$\newline$(D) $n \geq 1$ where $n$ is any number
